Abstract

A set special detecting system is proposed based on TDICCD push-broom technology applying in dynamic imaging detecting experiment of space optics remote sensor. In the system, push-broom movement of the satellite is simulated through using double supporting U structure precision rotary platform with remote sensor by angular speed 0.555°/s,within the range of ±5° and control precision on steady speed achieves 0.3%; In the course of detecting , regard Nyquist frequency target as detecting aim ,in order to solve matching uncertainty between the CCD pixel and the vertical target strip image when the remote sensor does push-broom, make matching simplify, enhance the measurement result the accuracy. So the tolerance a/n arithmetic progression gap target strip is joined in each group of rectangular vertical group target strip. The remote sensor obtains in vertical, the level and 45° the direction 0 fields of view, ±0.86 the field of view Nyquist frequency target strip image after detected, a group target strip which can precision matching to TDICCD pixel at least can be obtained through analysis and dealing with 0.86 field of view's target strip image. The experiment not only verifies the detecting system's feasibility but simultaneously verifies whether to have the high quality dynamic imaging quality when TDICCD push-broom technology is adopted on the remote sensor developed.
